OBJECTIVE: To reconstruct the anatomical glenoid shape in cases of osseous glenoid rim defects after recurrent posttraumatic anterior shoulder dislocation to restore stability without severely compromising the range of motion. INDICATIONS: Osseous glenoid defects after recurrent posttraumatic anterior shoulder dislocation. Suitable for primary stabilization as well as for revision surgery in cases previously operated on. CONTRAINDICATIONS: Recurrent anterior shoulder dislocations without glenoid rim defects. Hyperlax shoulders with multidirectional instability. Patients over 60 years of age due to compromised bone quality. Teenage patients due to incomplete apophyseal fusion at the iliac crest. SURGICAL TECHNIQUE: The subscapularis tendon and capsule are split. The humeral head is retracted laterally, and the glenoid defect is prepared and abraded with a rasp. A bicortical iliac crest bone block including crest and outer cortex is harvested and molded in a J-shaped manner. To incorporate the graft, a crevice on the glenoid rim is produced using a chisel. The keel is fitted into the preformed crevice with a spiked impactor. The graft's surface is contoured using a high-speed burr. RESULTS: A total of 47 shoulders were followed-up after an average of 90 months (range 25-152 months). The mean Rowe scores were 94.3 for the affected shoulder and 96.8 for the uninjured shoulder. The Constant scores reached 93.5 and 95 points, respectively. Loss of external rotation was 4.4°. In addition, 24 shoulders were followed-up by computed tomography (CT). There were no recurrences, with the exception of one traumatic graft fracture. Of 19 patients with arthropathy at follow-up, 11 already had arthropathy prior to the procedure.

There are many described surgical techniques for the treatment of recurrent anterior shoulder instability. Numerous authors have performed anterior bone block procedures with good results for the trea...

PURPOSE OF THE STUDY The aim of this retrospective study was to present a comprehensive overview of the causes of bone-tendon-bone (BTB) autograft failure after primary anterior cruciate ligament (ACL...

The anterior cruciate ligament (ACL) is one of the major stabilizing factor of the knee that resist anterior translation, valgus and varus forces. ACL is the most commonly ruptured ligament of the kne...

To determine (1) the relationship of a glenoid notch to the presence of a normal labral variant in the anterior-superior glenoid labrum; (2) the inter- and intra-observer reliability of recognising a ...

Medical and Biotech [MESH] Definitions

Bone-patellar Tendon-bone Graft

Fixation of the ANTERIOR CRUCIATE LIGAMENT, during surgical reconstruction, by the use of a bone- patellar tendon autograft.

Osteonecrosis

Death of a bone or part of a bone, either atraumatic or posttraumatic.

Cranial Fossa, Anterior

The compartment containing the inferior part and anterior extremities of the frontal lobes (FRONTAL LOBE) of the cerebral hemispheres. It is formed mainly by orbital parts of the FRONTAL BONE and the lesser wings of the SPHENOID BONE.

Host Vs Graft Reaction

The immune responses of a host to a graft. A specific response is GRAFT REJECTION.

Ethmoid Bone

A light and spongy (pneumatized) bone that lies between the orbital part of FRONTAL BONE and the anterior of SPHENOID BONE. Ethmoid bone separates the ORBIT from the ETHMOID SINUS. It consists of a horizontal plate, a perpendicular plate, and two lateral labyrinths.
